dm: Change the PCI_EMUL_MEMBASE64 to workable address. 

To enable GPU passthru, BAR2 allocation had problems when the allocation
is above the 4GB memory.This change is to accomodate the 256MB aperture
allocation in BAR2 to a more managable address.

v2: changed the MEMBASE64 address instead of increasing the mem_size.
